A 22-year-old Lehigh University student was robbed early Sunday morning by two men who implied they had a handgun.

The student was walking south on Boyer Street toward Summit Street about 12:32 a.m. when he heard the pair run up from behind him, Bethlehem police Lt. Mark DiLuzio said.

One man said, "Give me everything," while pointing something covered in cloth that the student took to be a gun, DiLuzio said.

Both robbers are described as black, ages 18 to 25 and wearing black hooded sweatshirts with bandanas covering their faces. One of the men weighs about 160 pounds and stands about 5 feet 7 inches while the other man has a similar build but is about 5 feet 10 or 11 inches tall, DiLuzio said.

The two men took the student's bookbag filled with textbooks, his cellphone, an iPod and $30 cash, police said. The men then ran north on Boyer Street.

DiLuzio warned people to stay on brightly lit busy streets late at night such as Packer Avenue. He said Boyer Street is an alley.

"You have to be aware of where you're walking and aware of your surroundings," DiLuzio said.

Anyone with information about the robbery is asked to call Det. Brad Jones at 610-865-7146.
